Concrete leveling floor crack repairing construction method
The invention discloses a concrete leveling floor crack repairing construction method which comprises the following steps: S1, crack reason judgment: dividing cracks into two types of hollowing cracks and telescopic cracks, and correspondingly marking the hollowing cracks and the telescopic cracks; s2, a V-shaped groove is formed, and drilling and grouting treatment is conducted on the hollowing and cracking area in advance; s3, a plurality of vertical kerfs perpendicular to the extending path of the crack are cut in the extending path of the crack at intervals, and reinforcing plates are inserted into the vertical kerfs correspondingly; s4, gap filling is conducted, epoxy resin is injected into the cracks from the V-shaped grooves, and meanwhile quartz sand is sprayed into the V-shaped grooves; s5, epoxy resin is injected again, and carborundum is sprayed into the V-shaped groove at the same time till the V-shaped groove is filled and leveled up; s6, when the epoxy resin is not completely dried, the crack repairing part is polished and flattened; the construction method can quickly, stably and economically solve the cracking problem of the concrete leveling floor.
本发明公开了一种混凝土找平地坪开裂修补施工方法，包括如下步骤：S1：裂缝原因判断，将裂缝划分为空鼓开裂和伸缩开裂两种并相应的做好标识；S2：开设V型坡口，对于空鼓开裂区域预先做好钻孔注浆处理；S3：在裂缝的延伸路径上间隔的切割出多条与裂缝的延伸路径垂直布置的竖向切缝，并分别向竖向切缝内插入加强板；S4：缝隙填充，由V型坡口处向裂缝内注射环氧树脂，于此同时向V型坡口内洒入石英砂；S5：再次注射环氧树脂，于此同时向V型坡口内洒入金刚砂直至将V型坡口填平；S6：在环氧树脂未完全干透时，对开裂修补部位进行打磨抹平处理；该施工方法能够快速、稳定和经济的解决混凝土找平地坪开裂问题。
